I wanted the content (including rich text + image) of document file stored in the databse to be displayed on the dynamic pages using Google doc app or pdf viwer app. But the option of 'connect to data' is not available for these apps. If it could have been possible, my site would have been been completed very quickly as just by adding data in my database would have created the whole page. If this is made possible, all the wix users will be benefitted. Looking forward for seeing this feature in more apps. This feature will give us, the users, more flexibility while creating dynamic pages.
